Introduction to cultivation techniques of large hazelnut in USA

Big hazelnut in the United States actually originated in China, but it was later introduced to the United States, where the yield and size of the plant are relatively large under the local climate type, so it is so called. Hazelnut looks like the chestnut we eat. It tastes very sweet and generally matures in autumn. Next, let's take a look at the introduction of American big hazelnut cultivation techniques.

I. the prospect of big hazelnut cultivation in the United States.

At present, the big hazelnuts sold in China are mainly imported, and there is no Pingou big hazelnut flavor, and the import price will also increase due to the impact of the trade war, which is also good for Pingou big hazelnut sales.

The development of Pingou big fruit hazelnut cultivation has good use and economic value. It not only tastes delicious as a snack, but also hazelnut is affirmed by many well-known experts and scholars in medicine, food, health care and other aspects. It is believed that it will be made into processed food as soon as walnuts and come into our lives.

Large hazelnut planting, there is a growth cycle, usually the third year hanging fruit, the fourth year to see the benefits, five years later gradually entered the full fruit period, the present stage of China's hazelnut industry has been from the initial stage to the rapid development stage, but most of them are young garden, seedling garden, or seedling-based dual-purpose mixed garden, the total output is not much. Therefore, the hazelnut industry in China is actually a seedling industry. It's not too late to enter. Very suitable for cooperatives, poverty alleviation projects and other large-scale cultivation.

2. Key points of cultivation techniques of large hazelnut in the United States

1. Preparation of the plantation

The establishment of the hazelnut garden is an important capital construction, which should be planned in advance. Water source power, drip irrigation and other facilities are a number of comprehensive supporting technologies that need to be considered in the hazelnut garden, which is not only related to the significant benefits in the later stage, but also an effective way to solve the current aging in rural areas and the lack of labor force. supporting mechanized operations that can operate mechanically can not only improve work efficiency, but also reduce labor pressure.

After determining the planting plot, the garden should be rotated to loosen the soil with a depth of 30 cm, clean up miscellaneous trees, weeds, stones and other debris, and build low platform fields in the land with poor drainage. If the mountain with a large slope, terraces should be built first and pay attention to the row spacing of planting. Gentle slopes can build horizontal ditches to intercept Rain Water and the soil washed down from the upper part.

According to 110 seedlings per mu, dig planting holes with plant spacing of 2 meters and row spacing of 3 meters. The planting hole is generally 60 cm in diameter and 40 cm in depth. When planting, soil dung is added or no soil dung is added. The depth of the pit is controlled by itself.

2. Variety configuration

The seedlings were planted according to the proportion of seedlings of each variety. David planted two rows and then planted two rows of new variety 2, and then planted two rows of new variety 3. Then plant two rows of Dawei for two rows of thin shell red, and so on. This is conducive to mutual pollination. If one variety is planted and replaced by another variety (you can mark it yourself).

3. Planting depth

The uppermost root system can be buried 6-10 cm in the soil, and the planting would rather be shallow than deep. After planting, do a good job of water storage plate irrigation, one-time irrigation, each plant needs to be irrigated 15-20 kg. After the water seeps, it can be fixed dry, and the fixed dry height is 40-60 cm. The cut is capped with lead oil or thin plastic film.

4. Points for attention

Although the big hazelnut tree is resistant to drought, it is after the second year, the seedlings that have just been planted are slow within two months, and the roots of the seedlings still need to grow. The moisture of the first year must be guaranteed. In July, you can apply a little compound fertilizer to the seedlings. Two taels of a tree is fine.

It is also important to remind everyone that atomization drift will occur during interplanting or medication in the farmland around the hazelnut orchard, which makes hazelnut leaves yellow and affects the growth of seedlings, which needs to be prevented.

After planting, loosen the soil and weed in time, enhance the soil permeability, promote the growth of new roots, and control diseases and insect pests. Pour antifreeze water once before the beginning of winter.
